Troy Davis Execution

From Wikipedia:

On September 7, 2011, Georgia set Davis's execution date for
September 21, 2011. The Georgia Board of Pardons and
Paroles set a hearing for Davis's second bid for clemency for
September 19. The Board did not grant him clemency in September
2008, but the five-member Board had three new
members. On September 20, the Board denied him clemency.

On the morning of September 21, 2011, the Butts County Superior
Court denied Davis's request to halt his execution. The Georgia
Supreme Court also denied his appeal. Davis was set to be
executed at 7 pm EDT. The same night, White House Press
Secretary Jay Carney announced that President Obama would not
intervene in the case. Davis filed a request with the
U.S. Supreme Court to stay his execution. Almost an hour after
Davis's scheduled execution time, the Supreme Court announced
they would review his petition, thereby postponing his
scheduled execution. The Supreme Court, however, denied
Davis's petition, after deliberating for several hours.

The execution began at 10:53 pm EDT. In his final words,
Davis maintained his innocence, and addressing the MacPhail
family said "I'm not the one who personally killed your son,
your father, your brother". He asked his family and friends to
continue the campaign. He was declared dead at 11:08 pm
EDT.

The GCP event was set for 8 PM to 2 AM local time. The result
is Chisquare 21494.147 on 21600 df for p = 0.694 and Z =
-0.507.

It is important to keep in mind that we have only a tiny
statistical effect, so that it is always hard to distinguish
signal from noise. This means that every "success" might be
largely driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect can
be identified only by patiently accumulating replications of
similar analyses.
